Lighting arrangement with battery backup

A lighting arrangement comprising:

• a light emitter portion having a plurality of light emitting diodes in an array string and circuitry for driving said plurality of light emitting diodes including a rectifier and an IC chip configured to drive said plurality of light emitting diodes with the rectified voltage provided by said rectifier, said light emitter portion also having a trim wherein said plurality of light emitting diodes in said array string and said circuitry mounted on said trim;
• a battery backup portion in electronic communication with said rectifier of said light emitter portion and having:
• a battery portion with one or more batteries and a converter portion with a DC-AC inverter, said converter portion connected to said rectifier and configured to receive power from said one or more batteries or a primary AC source, and said converter portion including a microcontroller unit, said microcontroller unit configured to route AC power to said rectifier from either the primary AC source or said battery portion when said light emitter portion and said battery backup portion are engaged with one another;
• said light emitter portion configured to be mounted to at least one of a wall and a ceiling during use;
• and
• said battery backup portion is positioned within said trim, with said plurality of light emitting diodes in said array string.
